6 >>A 51-year-old man develops pancreatitis associated with the passage of a gallstone. His treatment includes meperidine and intravenous normal saline. Two days later he becomes anxious, tachypneic, and short of breath. An emergency chest x-ray demonstrates diffuse, bilateral interstitial and alveolar infiltrates. A year ago he suffered a myocardial infarction, but since then he has had no evidence of congestive heart failure. In this case, adult respiratory distress syndrome can be distinguished from cardiogenic pulmonary edema by which of the following? ?

7 >>The same patient arrives in your office 72 h later with progressive symptoms. He is still complaining of continued low-grade fevers to 38.3
C (101
F). His cough is now productive of yellow greenish thick phlegm and is protracted, often resulting in vomiting. He denies any headache, sinus tenderness, or maxillary tooth pain. You prescribe which of the following? ?

8 >>A 25-year-old man with cystic fibrosis undergoes a double-lung transplantation. He is now 60 days posttransplant. He presents to your office complaining of malaise, low-grade fevers, dyspnea, and a nonproductive cough. His room air oxygen saturation is approximately 88%, his chest x-ray is unchanged from baseline, and spirometry shows a 15% decline from those results obtained 3 weeks earlier. A bronchoscopic lung biopsy reveals perivascular lymphocytic infiltrate. Which of the following would be the most reasonable next step? ?

9 >>A 72-year-old woman presents with an acute onset of pleuritic chest pain, dyspnea, and tachycardia 2 days after fracturing her left foot misstepping on an uneven sidewalk. During those 2 days the patient has spent most of her time bedridden. The patient is brought by ambulance to the emergency room. A ventilation-profusion scan (V/Q) is performed confirming the clinical suspicion ? ? of a pulmonary embolism. Which of the following treatment recommendations is likely to result in a decrease in a recurrent thromboembolic event? ?

10 >>A 35-year-old premenopausal woman presents with the diagnosis of pulmonary hypertension. She complains of dyspnea, nonproductive cough, and recurrent episodes of chest pain. Part of her pulmonary workup includes a bronchoscopy with a bronchoscopic biopsy. Histologic review of the biopsy specimen reveals pulmonary lymphangioleiomyomatosis (LAM). Which of the following statements concerning pulmonary LAM is correct? ?

11 >>Which of the following is a likely mechanism for this observation? ?

12 >>Which of the following statements concerning central sleep apnea (CSA) is true? ?

13 >>A patient with lymphoma who is known to excrete 1.5 g urinary protein per day has a negative dipstick evaluation for urinary protein. The reason for the seeming inconsistency is ?

14 >>A 75-year-old female nursing home resident is brought to the emergency department because of increasing obtundation. She is found to communicate poorly. Brief physical examination reveals diminished skin turgor. Blood pressure is 100/60, pulse 120, respiratory rate 20, and temperature 37�C (98.6�F). Blood tests reveal the following serum electrolytes: sodium 160 mmol/L, potassium 5.0 mmol/L, bicarbonate 30 mmol/L, chloride 110 mmol/L. The most appropriate management at this time would include administration of 5% dextrose in ?

15 >>A 45-year-old woman who has had slowly progressive renal failure begins to complain of increasing numbness and prickling sensations in her legs. Examination reveals loss of pinprick and vibration sensation below the knees, absent ankle jerks, and impaired pinprick sensation in the hands. Serum creatinine concentration, checked during her most recent clinic visit, is 790 ?mol/L (8.9 mg/ dL). The woman’s physician should now recommend ?

16 >>A 23-year-old man has recurrent episodes of hematuria over the past year. Each of the episodes seems to be associated with an upper respiratory infection. Physical examination currently is normal. Urinalysis reveals a relatively bland sediment; dipstick is positive for both protein and blood. Renal biopsy most likely will reveal ?

17 >>Which of the following case histories would most likely be associated with the urinary sediment depicted? ?

18 >>A 72-year-old woman with rheumatic heart disease is being treated with ampicillin and gentamicin for enterococcal endocarditis. One week into the course she develops a morbilliform skin rash and fever. Laboratory evaluation is remarkable for a doubling of serum creatinine and blood urea nitrogen from their baseline values. Urinalysis dipstick is positive for blood, protein, and white cells. Ultrasonography reveals bilaterally enlarged kidneys. Based on the available data, the most likely cause of the patient’s azotemia is ?

19 >>A 40-year-old woman who has never had significant respiratory disease is hospitalized for evaluation of hemoptysis. Urinalysis reveals 2 proteinuria and microscopic hematuria. BUN concentration is 7.1 mmol/L (20 mg/dL), and serum creatinine concentration is 177 ?mol/L (2.0 mg/dL). Serologic findings include normal complement levels and a negative assay for fluorescent antinuclear antibodies. Renal biopsy reveals granulomatous necrotizing vasculitis with scattered immunoglobulin and complement deposits. The most likely diagnosis in this case is ?

20 >>Which of the following patients is most likely to develop destruction of renal papillae with concomitant tubulointerstitial damage? ?
